I feel so bad for the dog! To be honest, I would want to take the dog just so that it would get attention and be loved, but I would be so wary of taking in a dog that neither I or my dogs had ever met. I also dont have the greatest opinion of doodle mixes. I think this is completely up to you, and what you feel is best for your family, as especially your dogs and baby! With a new baby, I would say no, just because a baby and 2 dogs is already a lot of responsibility.
